Run the arduino.exe program in your Arduino SE folder.Ħ. Download the Arduino library for Processing from here, and copy it into your Processing/libraries folder.ĥ.

Download the Processing Software Environment from here and extract it to a folder near your Arduino SE folder.Ĥ. Download the Arduino Software Environment from here and extract it to a folder (no installation required, just keep the folder in a safe place).ģ.

Connect the Arduino to your computer with your A to B USB cable (your computer should install its driver automatically) - see image 1.Ģ. Through a couple of small programs, your simple LED circuit will be dancing to the beat in no time.ġ. Programming the Arduino is pretty simple. Now that we have our circuit made, it's on to the programming. Run wires from the anode side of the resistors to digital pins 12, 8, and 2 on the Arduino to complete the circuit, as shown in image 6 and 7. Run wires from the cathode rail of the LEDs to the ground outer rail, as shown in image 5.ĥ. Place the LEDs right next to the right side of the resistors, with the anode (the longer end) in the slot right next to the resistor, and the cathode (the shorter end) into the slot that is offset to the resistors by 1 slot, as shown in image 3 (see image 4 to see the difference between an anode and a cathode).Ĥ.
Position the resistors so that they bridge the gap between the inner rails, as shown in image 2.ģ. This separates the left inner rails from the right inner rails, so you can connect more components. Note that on a breadboard, a line runs length-wise, halfway down the middle.
Place your three resistors (I used 1kilo-ohm resistors for this example, which matched my LEDs well enough) in an evenly-spaced fashion on the inner rails of the breadboard. Run a wire from the digital GND port of the Arduino to the negative outer rail of the breadboard, as shown in image 1.Ģ.

Here is how to make our simple circuit:ġ. The rails are electrically connected along their lines, so you can connect components without actually soldering them together. The breadboard has two parts: the inner rails (which run width-wise) and the outer rails (which run length-wise). From there FastLED does the heavy lifting of scaling down the brightness as to not exceed this predefined power limit.In order to have the Arduino access the LEDs, you have to build a small circuit on a solderless breadboard. The first number “5” tells FastLED that our strips use 5V power and the 2400 is the max output in milliamps. After defining your strip in the setup, you’ll want to add the line below. If you don’t want to get into the weeds with power, the FastLED library has a built in setting that will manage power for you.

The following would be example of colors with values less than or equal to 75.ĭon’t worry, 75 brightness is still plenty bright, to the point where you wouldn’t want to stare directly into an LED pixel. Here are a few options to consider. Think about how every section can be different colors in different order, increasing or decrease in brightness in different ways! The possibilities are endless!įor this battery and LED strip combo, keep the current (A) within the battery’s max output by not setting the RGB values of any color over 75. Since we are using customizable LEDs and can change every pixel, we have almost infinite options on how to make them look.

Even with zero programming experience you can make some impressive light effects.Īs a bonus! - At the end of the day a portable phone charger will still… charge your phone. With customizable strips, you can set every pixel to a unique color allowing for some amazing patterns and creative visuals. Rechargeable - While technically you could grab some rechargeable AAs, you then have the hassle of taking them out and making sure each AA is charged every time you want to use your LEDs.Ĭheap battery strips are typically non-customizable, meaning the most you’re going to get is the ability to change the color of the entire strip at once. Where a plastic case with 4 AA battles can hold roughly 15.6 watt-hours of power, a similar lithium ion portable charger can contain 50+ watt-hours with a power output 5x that of the AA batteries. Quality, bright LED strips, will eat up all of your precious battery power. Power output/power storage - There’s a reason we don’t charge our phones with AA batteries. Sure you can find cheap kits that hold a couple AA batteries with a small strip, however they have a few fatal flaws.
